Zhang Pankong, as Chen Mobai's good friend, came up with an idea after learning about this.
In the Tianhe Realm, the title of Rank-5 in the Hundred Arts of Cultivation Immortal, even if only in name, is extremely precious. Here, helping others refine carries no risk. Whether successful or unsuccessful, there is a benefit to be taken.
And of course, a Rank-5 Artifact Refiner will charge more for crafting a magic artifact.
Because of this, many cultivators stuck at the Fourth Rank Peak are willing to pay a high price for it.
According to the rules in the Tianhe Realm, whatever rank of profession you are borrowing, you need to offer a treasure of that rank.
For example, if Chen Mobai is refining a Fifth Rank Artifact, those wanting to participate as fire starters must at least offer a piece of Rank-5 ore.
